  • Publication number: 20240090209
    Abstract: A memory device includes a programming transistor and a reading transistor of an anti-fuse memory cell. The programming transistor includes first semiconductor nanostructures vertically spaced apart from one another, each of the first semiconductor nanostructures having a first width along a first lateral direction. The reading transistor includes second semiconductor nanostructures vertically spaced apart from one another, each of the second semiconductor nanostructures having a second width different from the first width along the second direction. The memory device also includes a first and a second gate metals. The first gate metal wraps around each of the first semiconductor nanostructures with a first gate dielectric disposed therein. The second gate metal wraps around each of the second semiconductor nanostructures with a second gate dielectric disposed therein.

  • Publication number: 20220250124
    Abstract: An apparatus includes a casing configured to be detachably mounted on a workpiece. The casing includes a first opening configured to expose a portion of the workpiece; a first support member coupled to the casing and constructed to move along a first axis through the casing and rotate around the first axis; a second support member coupled to the first support member and constructed to move along a second axis perpendicular to the first axis; an arm pivotally coupled to the second support member and constructed to rotate around a third axis perpendicular to the first axis and the second axis; and a cleaning head attached to the arm and constructed to rotate around a longitudinal axis of the arm. The casing includes a first plate and a second plate opposite to the first plate, wherein the cleaning head is configured to extend outside the casing through the first opening.
